iShared WAFS Optimisation Technology
Optimise application performance across the WAN. Minimise the amount of data travelling between your data centre and branch offices, and then make that data move faster. Native integration with Microsoft Windows or UNIX/Linux environments.WAFS Acceleration
iShared WAFS Acceleration delivers high WAN performance for Microsoft-based applications. Eliminate redundant data transfer as well as hundreds-even thousands-of CIFS messages traversing the WAN. Fully complies with industry-standard CIFS file sharing protocols. iShared's WAFS Acceleration features include:- Data streaming
- Read-ahead
- File-aware differencing
- Clustered I/O
TCP Acceleration
Swap out traditionally slow TCP with a transport protocol optimised for faster data transmission over WAN connections. Messages are acknowledged locally-no need to wait on remote responses suffering from latency. Large window sizes ensure that data is delivered much more efficiently than through small transmissions. Also, eliminate TCP "slow start" with iShared connection pooling for quick flow ramp up.Data Reduction
Make the most of precious bandwidth. Stop resource misapplication by cutting back on redundant and unnecessary data travel across the network.- File-aware Data Reduction Update changes only instead of duplicating entire files. File-aware intelligence tracks changes at the file and application level for faster response and highly economical bandwidth use.
- Dictionary-based Compression Track file changes locally at the byte level. Match repeated data blocks at either link end, transferring new datastreams only and not physical data to maximise bandwidth potential. Compression ratios of up to 100:1!
iShared WAFS and IT Services
Centrally manage IT services and ensure data integrity locally without compromising performance. iShared brings the power of the data centre to the branch office while extending added availability and security to the entire enterprise.Branch Office Networking
Access native Windows DNS/DHCP, domain controller, print and other IT services locally to avoid relaying over the WAN. Full compatibility with Microsoft Security. iShared provides a single point for branch office administration with automatic SMS software upgrades/patch distribution and an added layer of network monitoring.Application-intelligent Caching
Keep your most popular branch office applications up to date. With a quick check at data centre for changes, commonly used applications are promptly updated and opened.Distributed Filesystem and Single-instance Storage
Replicate data centre autonomy at the branch office. Local data management ensures data integrity and scalability without WAN vulnerability.- Distributed Filesystem
Extend the safe haven of the data centre to the branch office. Asynchronous write-back with synchronous logging to RAID disk helps retain "headquarter" control while ensuring data integrity and availability. Guaranteed 100 percent coherency via lock/lease management.
- Single-instance Storage Don't let network disruptions hang up operations. iShared extends Windows file access across the WAN while keeping files safe locally and automatically. No data "mirroring" needed at the data centre. Each branch office location holds its own, cutting down on the total cost of data storage ownership.
Disaster Recovery and High Availability Features
Keep business moving when disaster strikes by ensuring systems stay up and running.- Site-specific High Availability Enjoy high availability with no single point of failure. Configure redundant iShared systems in the data centre-or at the branch office-so one system takes over should the other system fail. The redundant system copies the active system in its idle time, staying up to date in the event it's called upon.
- Network-wide Disaster Recovery Support Remotely connect and synchronise data centre units to mitigate disaster effects where it's needed most. Build iShared's redundant system into your data centre disaster recovery procedures to automatically and transparently restore operations. If one system fails, a nearby mirror site can take over immediately with up-to-date data and state information.
- Hardware-based High Availability Features Avoid downtime due to hardware hang-ups. Ensure business continuity with iShared RAID and redundant power/cooling capabilities. Just plug new devices in without work disruption.
